Abstract: PROBLEM TO BE SOLVED: To provide a method and device for transferring variables to software routines by using stacks for holding the interchangeability of a program among microprocessors in different generations in a digital signal processor(DSP) for a a radio telephone or the like. SOLUTION: This DSP is constituted so that a variable length instruction can be used, and code density can be made high, and programming can be easily realized, and the structure and the instruction group are optimized so that a DSP algorithm can be executed with low power consumption and high efficiency. Variables are transferred to a sub-routine by using a user stack region 910, and a value indicating the first part of a program counter 1000 is held. Values indicating the residual part of the program counter 1001 are held by using a system stack region 911, and additional context information is held. The user stack region and the system stack region are independently managed, and software from a processor in the preceding generation is converted so that this software can run on a processor 100.
